Description
Fetch real-time and historical financial data from Yahoo Finance using yf-cli. Use when the user asks about stock prices, company financials, earnings calend...
Usage Guidance
This skill is internally consistent: it uses the yf-cli tool to get Yahoo Finance data and does not ask for secrets. Before installing, ensure you trust the provenance of the external tools it invokes (uv and yf-cli) and that your environment allows network access. If you are concerned about autonomous invocation, note the skill can run yf-cli commands when invoked by the agent — consider restricting autonomous use or reviewing logs. If you need stronger guarantees, verify the sources for uv and yf-cli (package repositories/releases) and inspect the yf-cli code you will install.
Capability Analysis
Type: OpenClaw Skill
Name: yf-finance
Version: 1.0.0
The yf-finance skill bundle is a legitimate tool for fetching financial data from Yahoo Finance using the yf-cli utility. It contains standard installation procedures via the 'uv' package manager in scripts/install.sh and SKILL.md, and provides comprehensive documentation for various financial queries. No indicators of data exfiltration, malicious execution, or prompt injection were found; the included Python snippets in assets/examples.md are strictly for data processing.
Capability Assessment
Purpose & Capability
Name/description match the behavior: SKILL.md instructs running yf-cli to fetch quotes, history, financials, news, etc. No unrelated binaries or credentials are requested.
Instruction Scope
Runtime instructions only call yf-cli and (in examples) simple one-liner Python processing; they do not reference unrelated files, secrets, or external endpoints beyond normal network access to fetch Yahoo Finance data.
Install Mechanism
No install spec in the registry; the included install.sh only checks for yf and runs `uv tool install yf-cli` if missing. This is a low-risk, expected install pattern (no opaque downloads or extracted archives in the skill).
Credentials
The skill requires no environment variables, credentials, or config paths. Its stated requirements (Python 3.13+, uv, yf-cli) are reasonable for running the described CLI tool.
Persistence & Privilege
always is false and the skill does not request persistent system-wide configuration or elevated privileges. The small install script only invokes uv and yf and does not modify other skills or agent configuration.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install yf-finance - After installation, invoke the skill by name or use
/yf-finance - Provide required inputs per the skill's parameter spec and get structured output
